If the distance between two objects is tripled, by what factor will the
gravitational force between them change?

  • Physics - ,

    1/(3^2) = ?

    That's called using the inverse square law.

  • Physics - ,

    but what is the 3^2 for? If the 3 is for the distance being tripled...what about the exponent 2?

  • Physics - ,

    Oh nvm, you mean

    F = 1/d^2

    Got it...thanks.

  • Physics - ,

    1/(3^2) = 1/9

    Square the distance ratio and put it in the denominator

  • Physics - ,

    if the separation distance b/w two objects is tripled is increased by a factor of 3,then the force of gravitation is decreased by a factor of 6
